Abstract
A previously healthy seven-year-old boy presented to the emergency room with a two-day history of abdominal pain and bloody stools. His pain was crampy and intermittent, and was isolated to the left side of his abdomen. His parents described bright red blood and passing of clots per rectum, in addition to episodes of melena. The patient had been afebrile, had no sick contacts, no significant travel history and no previous history of gastrointestinal bleeding. His appetite remained good. The family history was unremarkable for coagulopathies, inflammatory bowel disease or polyps. On admission, he was well hydrated, pale but nontoxic. His highest temperature was 38.1°C. He demonstrated an orthostatic heart rate increase from 120 beats/min to 140 beats/min, and a resting blood pressure of 102/42 mmHg. His cardiovascular examination revealed a grade II/VI systolic ejection murmur and normal capillary refill. He had a soft, nondistended abdomen with pain on palpation of the left abdominal quadrants. No peritoneal signs were present.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
